ONICON’s F-5000 Series Thermal Mass
Flow Meters provide accurate mass ﬂow measurement of natural gas, compressed air and other industrial gases. The proprietary sensor design measures mass ﬂow directly and does not require additional pressure or temperature compensation to deliver accurate ﬂow data.
The F-5100 is available as an inline or an insertion style meter. Both are provided with a bright, easy-to-read display and include a 4-20 mA output for ﬂow rate with a separate pulse output for totalizing ﬂow.

Every ONICON ﬂow meter is wet calibrated in a ﬂow laboratory against standards that are directly traceable to N.I.S.T. A certiﬁcate of calibration accompanies every meter.
Excellent Long Term Reliability -
ONICON thermal mass ﬂow meters employ a low maintenance, non-moving parts technology to sense ﬂow and are generally unaffected by debris in the ﬂow stream.
Highly Accurate Over A Wide Operating Range -
Our proprietary hybrid analog/digital sensing circuitry is very stable and yet highly responsive to changes
in ﬂow. This stable yet responsive design allows for accurate ﬂow measurement over a very wide operating range (over 1000:1 for the inline version). It also makes the meter ideal for measuring low ﬂow rates.
Provides For Field Validation Of Calibration -
The F-5100 continuously displays a special calibration value that provides a fast, easy way to conﬁrm that the calibration is valid.
Inline Meters are Provided With Built-in Flow Conditioners -
Flow conditioners are built in to all ½” through
4” diameter inline meters. The ﬂow conditioner signiﬁcantly reduces overall straight run requirements for installation.
Insertion Meters Can Be Installed Without Interrupting Gas Service* -
ONICON’s hot tap design allows for installation without interruption to the gas service. The meter can also be removed for service without disrupting ﬂow.
Excellent Value -
ONICON insertion style meters are
accurate, easy-to-use and reliable. They are also priced independently of pipe size. This makes them an excellent value, particularly in larger diameter pipes.

The optional D-100 Flow Display provides a local indication of rate and total and a network interface for BACnet, MODBUS, LonWorks, JCI - N2, or Siemens - P1 FLN networks.
